If there is no upstream information for a branch, it is likely that it
is newly created and can safely be pushed under the normal fast-forward
rules. Relax the --force-with-lease check so that we do not reject
these branches immediately but rather attempt to push them as new
branches, using the null SHA-1 as the expected value.
In fact, it is already possible to push new branches using the explicit
--force-with-lease=<branch>:<expect> syntax, so all we do here is make
this behaviour the default if no explicit "expect" value is specified.
